INK COMPOSITION.

No Drawing.

TocZZ whom it may concern Be it known that I, JOSEPH WILLIAM BALSER, a citizen of the United States, and a resident of El Dorado, in the county of Union and State of Arkansas, have invented a new and Improved Ink Composition, of

i which the following is a full, clear, and ex act description.

This invention relates to an ink composition, and has particular reference'to an improved penetrating ink or writing fluid.

An object of the invention resides inthe provision of a writing fluid which has particularly penetrating qualities, so that the necessity for the use of a blotter when using the ink is eliminated, and the ink is so incorporated in the paper that it is not possible to erase it therefrom without mutilating the paper. This has, of course, particular advantage in writing important documents and papers, such as bank checks. By the use of this ink the necessity for expensive machines for perforating or otherwise affecting a check so that it cannot be erased is eliminated.

Another object resides in the provision of a composition which is very simple and inexpensive to make and the strength. of which can be varied very readily as desired.

'The composition which forms my invention includes the use of the following ingredients,namely: carbolic acid, denatured alcohol, water, sugar, and a dye or other coloring matter.

In the formation of the composition, for example, in order to make a gallon of it, I use substantially the following proportions:-

84: ounces of oarbolic acid.

60 ounces of denatured alcohol.

20 ounces of water.

13 ounces of sugar.

1 ounce of Diamond Dye.

Application filed June 24, 1922. Serial No. 570,726.

The alcohol is first mixed with the carliolic acid, to which mixture the dye is added. The sugar is then dissolved in water and added to the other ingredients. The fluid is then allowed to stand open in the air from six to nine days.

After this ink has been used on paper or other fabric, it is found that it is impossible to erase it or to remove it with chemicals without. mutilating the paper. This makes the use of the ink very desirable for writing bank checks, legal papers, or other documents of importance. v

In order to accommodate the ink to different kinds of paper, it may be necessary to slightly change the proportions of certain of the ingredients used, such as the acid, in order that the ink can more effec- 'vely penetrate the paper.

it will, therefore, be observedthat I have provided a simple and inexpensively manufactured composition for use as writing fluid. It can be very readily prepared without any particular complexity in the process ofmanufacture. It is, of course, understood that the proportions of the ingredients can be varied within reasonable limits to vary the strength of .the fluid without departing from the spirit of the invention, which is mainly concerned with the use of the acid, sugar and the Diamond Dye in proportions varying within reasonable limits.

\Vhat 1 claim is:

1. A writing fluid which includes the use of carbolic acid, sugar, a dye,denatured alcohol andwater.

2. A writing fluid which includes the use of thirty-four ounces of carbolic acid, sixty ounces of denatured alcohol, twenty ounces of water,'th1rteen ounces of sugar, and one ounce of a d y JOSEPH \VILLIAM BALSER.
